Prototype Cat Tractor and Road Groomer

[Supermario]

Great looking start to the build. I like the use of the grader cab reversed on the engine cowl, it doesn't look out of place to me.
What do you plan on using to add weight to the groomer? As it sits I don't think you'll get much penetration and probably just skip along.

Thanks.
To be effective, the groomer will indeed need some weight. Plenty of room to place lead strips here and there. Also, the depth the teeth can penetrate are limited by the side skirts...



Deep dish OEM Wheely King mags don't seem appropriate so some Hummer wheels are cut and glued into the lips. The holes will be covered with center caps later...

more done today...

The rear axle has bosses for the servo plate...



So used them to mount an scx10 battery plate. 2 out of 3 holes lined up and also added another:



Finished mocking up a lift system for the implement. It doesn't look scale but it does keeps it straight and steady. Also lifts up nicely past the fulcrum point to relieve stress on the servo while in the up position. Plus the servo can exert down pressure to help the implement dig in more than it would on its own:

Added some Gearhead beadlock bolts today. Center caps to follow.



And fabbed an ESC/receiver box behind the cab (needs lots of sanding work)

Added a plow for next winter. The lift mechanism is next.

I like the creativity of this build and has given me a few ideas for a custom build. Keep the updates coming and can't wait for a video.

Thank you very much!
